GREASE nIsPiszNslm Application llled Hay 15, 1922, Serial No. 561,080.ilenewed December 3, 1930.

Our' invention relates to dispensing apparatus for plastic andsemi-fluid materials, more particularly to an apparatus fordischarginggreases, oils, aste or heavy or Nviscous Huid in measured) quantity.

The present application is a continuation in part our pendingapplications for Letters Patent Serial No. 453,97 8 filed March 21,

the commodity during such period of operation, by eliminating airpockets in the body of the discharged'commodity, and preventing backleakage'in the feeding mechanism.

The object of the invention 1s to simplify the structure as well as thelmeans and mode of operation of such apparatus, whereby it will notr onlybe cheapened in-construetion, but' will be ffno're efficient in use,positive in operation, uniform in action, accurate andv unlikely to getout of repair.' f. l

A further object of the invention is to provide a one man apparatus,wherebya single operator in charge of the discharge nozzle, ata remotepoint from-the supply reservoir and feeding apparatus, may control such`apparatus, wlthout necessitating a second operator for manipulating thedispensing mechanism. The structure is 'particularly-applicable forfeeding lubricant or grease 1n a garage for filling transmission anddiferential casings of motor'l vehicles. With the type of apparatus nowin common use, one operator is requiredjto 'operate the pump ordispensing means', while a second operator holds the nozzleof thedischarge hose or conduit in the supply orilice of the transmission ordifferential casing, and signals the pump' operator when grease is tobesupplied or its supply arrested. The present invention is designed toplace the entire operation under control of a single operator who ischarge modity. This timer, involves an automativcally driven circuitbreaker which will' interrupt the motor circuit with minimum arcing,with means for again setting it in operation from a distant polnt.

' A further object of the invention is to provide adjustable means bywhich the extent of the periodic operation may be varied to accommodatethel apparatus to feeding commodities lof different consistencies ordifferent character.

A further object of the invention is tp proj vide an improved form ofauxiliary pump or booster with means forpreventin any yieldy ing orleakage under influence o back pressure, thereby insuring the deliveryof a full measured quantity at each operative period.

A further object of the invention is to provide improved screw feeddispensing means of such character anfd capacity in relation with thedischarge capacity of the apparatus, as to effectively prevent theforming of airv pockets and the assurance of the delivery of acontinuous and solid stream of dispensed commodity.

With the above primary and other incidental objects in view as Will morefully appear in the specification, the invention consists of thefeatures of construction, the parts and combinations thereof, and themode of operation, or their equivalents asA hereinafter describedlandset forth in the claims.

Like parts are indicated by similar characters of reference throughoutthe several views.

Referring to the drawings of the preferred embodiment ofthe invention, 1is the container or reservoir for the material to be dispensed inmeasured quantity. This reservoir or container rests upon a base 2,within which is contained the ejecting apparatus.

The base or housing; `2.is provided with an ocket or chamber 4,.withwhich the open ottom of the reservoir or container 1 open registers.'Within the bottom of the chamber or pocket 4 of the base 2, there areformed a plurality of parallel semi-circular grooves or recesses 5,terminating at one side of the chamber 4 in concentric bores or circularpassages 6, which form continuations of the grooves 5, in the base orhousing 2, and which extend beyond the chamber or receiving pocket 4.Located in each of the semi-circular grooves 5 and extending thenceintothe corresponding bore or passage 6, is a revoluble spiral conveyor 7.There may be any number of these spiral conveyors in the series.

In the drawings, but four have been shown. It is obvious that more orless number of such conveyors ma' be employed. The conveyors 7 extend asu cient distance through the passages or bore 6 to afford ample bearingtherein, for one end of the conveyor screw,`while at their o positeends, they are provided with suitale bearings in the wall of the chamber4 .and are furthermore linterconnected one with the other, for rotationin unison by intermeshing gear pinions 10.

Asv shown in the drawings, the pitch of the succeeding conveyor screwsis reversed, and

y these conveyors are rotated in reverse direcmeter casing being I i-conveyor facilitates the gathering o tion by the intermeshing gearpinions `10, whereb the conveyors simultaneously advance t e plastic orsemi-fluid materials uniformly in the same direction, that is to say,toward the bores 6, through which the commodity is discharged from thechamber 4. Inpractice, the rotation of these screws, one toward theother, forms intermediate the conveyors of each pair, a ridge ofmaterial, which is uniformly advanced toward the discharge ends oftheconveyors within the bores 6, as the conveyors are4 rotated. It will benoted in Fig. 4, that the pitch of the conveyor screws is not uniform,.but gradually decreases as it approaches the discharge end of theconveyor screw. This variable itzlh t e commodity'from the distant sideof the container or reservoir, advancing it toward the discharge outlet,where it is subject to gradually increasing pressure, as the rate ofspeed across the chamber 4 decreases.

The trunnion shaft of one of the conveyor screws extends beyond thechamber 4, as indicated at 11, to afford a driving connection for theseries of conveyor screws, 7. VThese consion 11, of the initial screwconveyor of the series is provided with a bevel gear pinion 12,meshingwith a like pinion 13 upon a vertically disposed power shaft 14.The -drive shaft or power shaft 14, carries a worm wheel 15, withv whichmeshes a driving worm upon the armature shaft vof an electric motor 17.Upon the operation of the driving motor 17,

'the spiral conveyors 7 are simultaneously actuated through theiniiuence of the worm 16, meshin `with the Iworm wheel 15 upon the powersha t 14, and interconnectin pinions 12 and 13 to discharge the commoity from the container or reservoir 1, through the lateral bores 6 ofthe Ybase 2, into la pressure communicate with this pressure chamber,and

simultaneously discharge thereinto.

To provide for hand manipulationpin the event of an emergency, or foruse under abnormal conditions, the upper endlof the power shaft 14 isprovided with a bevel pinion 19, meshing with a similar gear upon atransverse. shaft 20, to which maybe connected a detachable hand crank21, for hand actuation of the apparatus. To permit such operationindependent of the motor` 17, the

worm wheel 15 is preferably though notv necessarilyy connected tothe=power shaft/14;

by means of a pawl and ratchet connection,"..

shown at 22, whereby the power sha-ft 14 may' be rotated in an advance`or forward dile'ction by means of the hand crank, -independent of theworm wheel 15, during which advance movement, the pawl will ride idly,over the teeth of the ratchet wheel. However, upon operation of themotor and consequent rotation of the `worm wheel 15, the pawl carried bysuch worm wheel will operatively engage the ratchet wheel which isfixedly secured upon the power shaft to drive the power shaft in unison.Such pawl and ratchet c onnection is shown for illustrative purposesonly. it being obviousthat any suitable form of engaging clutchmechanism may be substituted therefor.

Leading from the pressure chamber 18 of the base or housing 2, is adischarge. conduit `comprising preferably a flexible hose 23 of suchcharacter as to withstand the high pressure under which the commodity isdelivered. There are upon the market at the present time, various formsof metallic flexible hose and metal bound or armored hose, which aresuitable for this purpose. Located at the outlet of the pressure chamber18 to the hose connection 23 is a rotary power driven meter 24,comprising a cylindrical housing 25, having inlet and outlet passages 26and 27. Mounted eccentrically within the circular housing 25, is a rotor28, having therein two oppositely disposed overlapping slidlng blades orvanes 29. These vanes are slotted or formed with registering recesses intheir inner or overlapping portions to receive springs 30 by which theblades or vanes are forced apart, and against the wall of the housing 25as the rotor 28 revolves. During the rotation of the rotor, the bladesor vanes reciprocate to and fro therethrough, due to the eccentricity ofthe wall of the housin 25, and the axis of rotation of the rotor. heblades or vanes maintain, lat all times, their bearing contact upon theinterior Walls of the cylinder under the influence of the springs 30.'

The rotor 28 is positively driven by means of a bevel gear 31, upon therotor shaft, which intermeshes with a similar gear 32, upon an extendedstem or shaft of one of the spiral conveyors 7, which projects throughthe pressure chamber 18, and through a suitable stuffing box, 33A, tosupport on its outer end, the said gear pinion, 32. The rotary meter isthus positively driven in unison with the actuation of the spiralconveyors 7.A The capacity of the spiral conveyors 7 1s very muchlgreater than the capacity of the meter, through which the dischargedcommodity must pass. The result of this preponderance of feedingcapacity of the conveyor 1s to maintain a supply of commodit underpressure within the chamber 18. he conveyors feed the commodity to thechamber 1.8 very much faster than the meter, will permlt it to dischargetherefrom. The result is that the surplus material is squeezed back,along the spirals of the conveyors 7. but the chamber 18 is alwaysmaintained lled to its en" tire capacity. vOneiof the purposes of thisoversupply of commodity to the chamber 18,

in quantitles greater than is permitted to escape lthrough the meter, isto insure the avoidance of air pockets and to assure a continuousdischar e of uniform density. Any en# trappe air is permitted to escaperearwardly through the bore 6 with the surplus material, which issqueezed backwardly or overflows the spiral flute of the conveyor.Without some such provision, the feeding of the commodity would bespasmodic and the discharged material would be inclined to splutter dueto the expansion of small pockets of vcompressed air as the materialleaves the clischarge nozzle. Moreover, there would be no assurance offull measured quantity. The quantity discharged would vary as part ofthe bulk would be compensated forby such pockets of air.' Moreover, insuch case the entrapped or entrained pockets of air would conducevarying density of the material at different points in the discharge.

By providing the vfeeding apparatus and the meter in tandemrelation, butwith different capacities whereby the meter is supplied with a quantityof commodity greater than its capacity to measure, a full charge to themeter is insured at each rotation, and the density of the successivecharges will be uniform.

In order to prevent back leakage, through the meter, or any slightvariation of the blades or vanes of the meter rotor, due to backpressure within the discharge conduit 23, means is provided foradvancing theblades or vanes into close operative contact with the.walls of the4 meter casing' 25, during the operative stroke of suchblades or vanes. 'l This positive actuating means for the meter'bladeoperates entirely independent of the spring 30. It consists of notchesor grooves 33 formed in the ends of the vanes or blades 29, which engageover-cam beads or flanges 33',

projecting inwardly from the heads of the.

meter casing 25. The construction is such that as the blade 29approaches its operative position or point of greatest stress, that isto say, as it passes the inlet orifice 2'6-,fthe notch orv oove 33 ridesover they flange orl bead 33', which is arranged in such concentrirelation with the path of travel of the blade or vane, that it willserve to maintain the blade in operative bearing-relation with thecircular wall of the meter casing 25. The ends of the retaining bead orflange 33 are beveled or reduced somewhat in' thickness to afford acamming action and facilitate the engage-f retraction under excessiveback., pressure,

throu hout its `operative stroke from the inlet orifice 26 to the outletorifice 27. It will ,"be obvious that as the ,rotorf 28 advances, the

s ace intermediate the rotor 28 and wall of t e meter casing immediatelyin the rear of the blade or vane 29 willbe filled with the commodityunder pressure of the feeding screws 7. Th1s space will continue toreceive such commodity until the blade approaches the outlet orifice 27,at which time the opposite blade 29 is in position to pass the intakeorifice 26, and by itsadvance force the charge received within thecasing 25, forwardly toward the outlet 27. At each operation thisvcharged space is completely filled under uniform pressure. The chargecapacity of this space being known, a predetermined quantity of thecommodity may be delivered by limiting the operation of the meter to apredetermined number of rotations of the rotor.

In order to regulate the discharge of commodity by limiting the periodicoperation of the apparatus to a prescribed number of rotations of themeter, there is provided a timing mechanism or regulator operating inunison with the motor.17, but adapted to open the motor circuit when apredetermined number of revolutions of the meter has been effected.While such regulator might be located in close proximity tot-he meter,as in our prior application referred to, or closely associated with themotor if so desired, it has been in the present instance located on topof the apparatus and is driven from the power shaft 14. vTo this end,the jack shaftv 20, which is mounted in suitable bearings on anextensionor shelf 34, projecting from the top frame of the reservoir or container1, carries a worm 36, meshing with a worm wheel 37, forming the initialelement of .theregulator. This worm wheel 37 ismounted for rotation upona vertically disposed shaft orl stud 438, carried by an oscillatory arm39, pivoted at 40 on top of the shelf like projection 34, of the frameof the apparatus.-

The oscillatory arm 39, isprovided with lateraly ears to accommodate anarcuate slot 41, through which engages a clamp screw 42.

The adjustability of the swlnging arm 39, which may be engaged indifferent positionsV by the clamp screw 42, is to accommodate worm theapparatus to commodities of different .65 densities. For instance, if itis desired to deliver at each cycle of' operation, one poundofy a heavygrease, a smaller worm gear may` be required than to deliver one poundof a' light grease. In changing from one char- 65 acter-of commodity toanother, a test run segmental wall into one ofthe openings 54,

may be made and accurately weighed to determine whether a longer orshorter cycle l of operation is necessary to. feed the requiredquantity. The worm gear 37 rotates loosely upon the stud 38, and isprovided with an upwardly directed hub portion 43, within the hub 44 ofa housing 45stationarily supported upon the apparatus the wall of whichforms one terminal of a make and break switch in the motorcontrolcircuit. The hub 43. of the worm gear 37 is insulated from thehousing 45, by an interposed sleeve 46 ofy .insulating material. Thewheel 37 isl further preferablyv recessed for a collar 48, of insulatingmaterial, such as fiber, upon which the end of the hub 44 abuts.Surrounding the stud 38, immediately above the hub 43 of the worm gear,is a fiber disc or collar 49, operatively engaged with the worm gear 37,by means of a stud. or pin 50, and in turn engaged .with a rotating arm51, by means of a second stud or pin 52. A disc of fiber or insulatingmaterial 53 is located in the bottom of the housing 45, beneath the arm51. The construction is such that the housing is entirely insulated fromthe arm 51, or any of its vconnecting parts. The housing 45 is heldstationary, by any suitable connection, 45 with'the frame oftheapparatus, while the arm 51 rotates within such housing, in unison withthe worm gear 37, but normally insulated from the housing.

The circular wall of the housing 45 is formed with a series of spacedopenings Aor notches 54, affording there between a seriesl 1.00 l

of spaced contact segments which are elect-ricallyA connected into the'control circuit. There-may be only one of these openings or notches, inwhich event, the regulator arm 51 will make a completerotation at eachcycle 135 of operation, or as shown in the drawings, there may be aplurality of notches or recesses 54 affording a series of contactsegments with which the motor controlled circuit is successively closed.

The rotatin larm 51 carries a spring actuated contact nger 55, pivotedvat 56 to said arm 51 with -which it is also electrically connected, and.normally actuated into wiping, engagement with the segment formed bythe 115 notched wall of the housing 45 bythe spring 57. This finger 55forms one terminal of a make and break switch the opposite terminall ofwhich may be any'one of the segments of the wall housing 45 is formed bythe notches Vor recesses 54. The finger 55 is also provided with a stopstud 58 engaging a projection or stud 59, to limit the throw of thefinger, 55 under the iniuence of the spring 57 when such finger passesoff ofthe arcuate wall of the housing into one of the notches 54. This Awipe finger 55 by its engagement with the arcuate wall ofthe housing 45,completes the motor circuit and when it passes olf such its suddenadvance movement under the in- 4iuence of the spring serves to quicklybreak rotating arm 51 is held in engagement with the driving gear bymeans of a tension spring 51, abutting at its lower end upon the arm 51,and at its yupper end seated within an overhanging cap 60. The regulatoror timer is preferably covered by a disc 61 of glass or othertransparent material held in place by a flanged collar 62. Thisregulator is included in the motor circuit, by grounding one side of themotor upon the frame of the apparatus, or otherwise connecting itelectrically with the rotating arm 51. One side of the current supplycircuit is then connected with the motor and the other side with thehousing 45, so that a circuit is completed by the wiping contact withthe finger 55, with the segmental wall of the housing as the arm 51 isrotated. This connection will be clear from an examination of Fig. 5,wherein the electrical circuits are shown. It is obvious that so long asthe wipe finger is in engagement with the segmental wall 'of the housing45, current will be supplied to the motor and the apparatus willcontinue in operation. I-Iowever, as 4the wipe finger approaches one ofthe notches 54, and is actuated by its spring to break the electricalcircuit, the motor will be brought to rest. In order to initiate theoperation of the apparatus, it is necessary to bridge this open contactbetween the wipe finger 55, and the housing 45. This in the presentinstance is effected by means of a push button upon the discharge nozzleof the conduit 23. At the extremity of the conduit there is provided anozzle 63, preferably having therein a cut-off valve 64. Located on theside of the nozzle 63, adjacent to the cutoff valve is an electricalpush button 65, from which conductor wires lead, preferably through thedischarge conduit to the apparatus and thence across the gap afforded byY the wipe finger 55, and the contact wall of the housing 45. Thisconnection is shownv diagrammaticall in Fig. 5, where it is obe viousthat by c osing the push button 65,

momentarily, the motor will be actuated to advance ythe wipe fingeruntil it engages "the'segmental wall of the housing- 45whereupon thepush button 65 may be released, and

55 `the motor will continue its operation, until the next notch oropening 54 is engaged by the contact nger 55.- v

The purpose of mounting thisl `,control switch 65 upon the dischargenozzle, is toenable the apparatus to be controlled by a single operator.The dicharge conduit 23, may be of any suitable length, and 'whateverits length may be, the operator who holds the .discharge nozzle andtherefore observesthe flow4 of the commodity, hasabsolute control of the`starting of the apparatus. The apparatus when once started willcontinue its operation until the predetermined quantity is delivered.This quantity is preferably predetermined in pound or pint lots. That isto say, thel apparatus is so designed and the gear ratios of the wormdrives 36 and 37, so I proportioned that one pound or one pint ofcommodity will be delivered while the arm 51 rotates to carry its wipefinger 55 from one opening 54 to the next one.

As a matter of safety, the valve 63, uponv provided witha lid 66 havingan upstanding f hollow standard 67, provided with a lateral accessopening 68, into which the end of the nozzle may be inserted. when notin use. To this end the nozzle is provided with a pin or finger 69, bywhich it may be operatively engaged in the opening 68, by hanging ittherein.

From the above description it w'ill be apparent that there is thusprovided a device of the character described possessing the particularfeatures of advantage before enumerated as desirable, but whichobviously is susceptible of modification in its form, proportions,detail construction and arrangement of parts without'departing fromtheprinciple involved or sacrificing any of its advantages. i

While in order to comply with the patent statute the invention hasbeen-described in language more or less specific as to structuralfeatures, it is to be understood that the invention is not limited tothe specific details shown, but that the means and construction hereindisclosed comprises the preferred form of severalmodes of putting theinvention into effect, and the invention is therefore claimed in any ofits forms or modifications within the legitimate and valid scope of theappendedclaims, v
